IP Address
Setting Factory Default Necessity
E.g., 192.168.1.1
(IP addresses of the form x.x.x.0 and
x.x.x.255 are invalid.)
192.168.127.254 Required
An IP address is a number assigned to a network device (such as a computer) as a permanent
address on the network. Computers use the IP addressed to identify and talk to each other over the
network. Choose a proper IP address which is unique and valid in your network environment.
Netmask
Setting Factory Default Necessity
Ex. 255.255.255.0 255.255.255.0 Required
A subnet mask represents all the network hosts at one geographic location, in one building, or on
the same local area network. When a packet is sent out over the network, the NPort will use the
subnet mask to check whether the desired TCP/IP host specified in the packet is on local network
segment. If the address is on the same network segment as the NPort, a connection established
directly from the NPort. Otherwise, the connection is established through the given default
gateway.
Gateway
Setting Factory Default Necessity
Ex. 192.168.1.1 None Optional
A gateway is a network gateway that acts as an entrance to another network. Usually, the
computers that control traffic within the network or at the local Internet service provider are
gateway nodes. NPort needs to know the IP address of the default gateway computer in order to
communicate with the hosts outside the local network environment. For correct gateway IP
address information, consult the network administrator.
IP Configuration
Setting Factory Default Necessity
Static
DHCP
DHCP/BOOTP
BOOTP
Static Required
ATTENTION
In Dynamic IP environments, the firmware will retry 3 times every 30 seconds until network
settings are assigned by the DHCP or BOOTP server. The Timeout for each try increases from 1
second, to 3 seconds, to 5 seconds.
If the DHCP/BOOTP Server is unavailable, the firmware will use the default IP address
(192.168.127.254), Netmask, and Gateway for IP settings.
